Recurrence in Benign Paroxysmal Positional Vertigo: A Large, Single-Institution Study

OBJECTIVE:To report rates of recurrence in benign paroxysmal positional vertigo (BPPV) and associated patient and disease factors. STUDY DESIGN:Retrospective chart review. SETTING:Single high-volume otology practice. PATIENTS:Patients diagnosed with BPPV from 2007 to 2016 with documented resolution of symptoms. INTERVENTION:Diagnostic and particle repositioning maneuvers for BPPV. MAIN OUTCOME MEASURES:BPPV recurrence, time to recurrence, and ear(s) affected at recurrence. RESULTS:A total of 1,105 patients meeting criteria were identified. Of this population, 37% had recurrence of BPPV in either ear or both ears. Overall same-ear recurrence rate was 28%; 76% of recurrences involved the same ear(s) as initial presentation. Recurrences that occurred after longer disease-free intervals were more likely to involve the opposite ear than early recurrences (p = 0.02). Female sex (40.4% versus 32.7%, p = 0.01) and history of previous BPPV (57.5% versus 32.4%, p
